Answer:

Step-by-step explanation:
<u>What number</u> <u>divided by</u> <u>-7</u> <u>is equal to</u> <u>-15</u>
∨ ∨ ∨ ∨ ∨
x ÷ -7 = -15
Multiply -7 to both sides:


3x+2 mulitiply by 2. you will get 6x+4 now put 10x-12 like so 6x+4=10x-12. then use like terms and subtract 6x from 10x. you will get 4x-12=4. then add 12 to cancel out then divide 16 by 4 and then x=4 then plug in 4 to replace x in 3x+2.
The answer is 14
